In particular to a sand-containing sampling device which intercepts sand in water and adsorbs the sand by collecting and gathering.
Background
At present, in water conservancy water quality detection, the detection of the sand content of water quality is particularly important, but because the silt in natural water quality is mostly suspended sediment, the uniformity is poor, the sand content is distributed along the vertical direction differently, the sediment with higher density is positioned at the bottom layer, the silt content is measured at present by firstly collecting the silt and then carrying out layered separation on the silt of the suspended matter, because the separation is needed, the filtering is needed after the separation, the quality difference before and after the calculation of drying filter paper is realized, the operation steps of the whole process are complicated, sampling points with larger errors are not specific enough, in order to ensure that the silt at the suspended position is collected, the collector needs to be suspended in the water body, but because the water quality flows, the collector floats in the water flow, the silt in the water body can not be rapidly gathered, and large particles at the bottom layer can be impacted into the collector along with the flowing and scouring of the water body, the silt can not be collected along the flowing direction of the water body, the collection work of a collector is influenced, a collected water sample needs to be filtered after collection is finished, the water is dried after being filtered, the mass of the silt is weighed, the sand content is obtained, the silt is required to be filtered independently, the detection sampling time is long, and the error is large;
the publication number CN105092297A discloses a vertical measuring point sand content sampling device, which comprises a plurality of sampling tubes, wherein water inlets of the sampling tubes are arranged at different heights of the same vertical straight line, the upper ends of the sampling tubes extend out of the water surface and are fixed on a fixing device, an outlet at the upper end of each sampling tube is connected with an independent guide tube, a valve is arranged at the part of each guide tube extending out of a test water tank, and a positive-negative two-way air pressure valve is connected on the side wall of the guide tube above each valve; the tail end of each conduit is connected with an independent online sand content tester; and the fixing device is provided with a longitudinal adjusting bolt and a transverse adjusting screw rod for adjusting the longitudinal and transverse distances. When the water sample is collected, a global coverage mode is adopted, all points on the vertical height are collected, the whole equipment is huge, more pipelines are difficult to maintain, and the arrangement of the collection points is different due to different depths of water bodies, so that the adjustment cannot be carried out;
publication No. CN105738152A discloses a large-scale deep reservoir layered continuous silt collecting device, which comprises a floating platform, a rotating handle device, a pulley assembly, a cable, a suspended silt collecting barrel, a silt suspended mass collector, a balancing weight and a triangular fixed support; the problems of difficult maintenance and high cost in layered observation of the sediment suspension of the large deep reservoir are solved, and the problems of difficult acquisition of the layered sediment suspension of the large deep reservoir and insufficient representativeness of single-point acquisition are solved. The invention aims at the reservoir to collect, the water quality fluidity is weak in the reservoir range, the suspended sand collecting barrel can be fixed through the cable, but the suspended sand collecting barrel swings along with the water flow at the position with larger water quality flow velocity, and the silt collection is difficult to continue.
